CONTROL STRUCTURE FOR AUTOMATICALLY OPENED AND CLOSED UMBRELLA - An improved control structure for automatically opened and closed umbrella is provided. The control structure contains a one-way wheel linked to a string of a bullet head or an upper nest, and further contains a locking arm and a positioning arm. When the umbrella is compressed, a vertical section of the locking arm moves towards and presses against the one-way wheel's ratchets. As such, if the umbrella is accidentally released during its closing operation, the one-way wheel is locked by the locking arm and the bullet head is therefore locked as well. The compressed shaft is then immediately positioned without being affected by the suddenly released opening spring. The umbrella is therefore much safer to operate.
